Q1. In a cluster environment, what role does a distributed lock manager (DLM) play?

🔹 A. It manages keyboard input across multiple terminals.

🔹 B. It coordinates access to shared storage or resources across nodes to prevent data corruption in concurrent access scenarios.

🔹 C. It encrypts network traffic between nodes.

🔹 D. It balances the electrical load across the cluster power supply.

💡 Difficulty: medium | ✅ Correct: B

Q2. How does 'single-system image' (SSI) differ from standard clustering?

🔹 A. SSI makes the cluster appear as one unified computer to users/apps, hiding node boundaries; standard clusters expose individual nodes.

🔹 B. SSI requires all nodes to be identical hardware; standard clusters do not.

🔹 C. SSI is only possible on mainframes; standard clusters use PCs.

🔹 D. SSI eliminates the need for networking between nodes.

💡 Difficulty: hard | ✅ Correct: A
